Question

Today only, a desk is being sold at a 35% discount. The sale price is $429.What was the price yesterday?

Answer 1

Given:

The discount for the desk today, D=35%.

The sale price, SP=$429.

The expression for sale price is,

`SP=(100-D)/(100)* CP`

Here, CP is the price yesterday.

Substitute the known values and solve for CP.

`\begin{gathered} 429=(100-35)/(100)* CP \\ 429=(65)/(100)* CP \\ CP=(429*100)/(65) \\ CP=660 \end{gathered}`

Therefore, the price yesterday is $660.
